Download or read book Use of Geotextiles with Enhanced Lateral Drainage in Roads Over Expansive Clays written by Ivan Enrique Garcia Delgado and published by . This book was released on 2015 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expansive clays are very abundant across the central United States in general and in the state of Texas in particular damages induced by expansive clays have been reported to reach several billions of dollars per year. Volume changes in expansive soils due to change in their moisture content varies has caused significant cracking in roads and has resulted in costly maintenance projects over the lifetime of these roads. In Texas, expansive soils have been often treated with lime stabilization, which is not always possible, and in some cases by removing and replacing them with nonexpansive soils, which can be very costly. Recently, geosynthetic reinforcements have been incorporated in roads founded on expansive clays to make the structure stiffer and less prone to cracking. A new geotextile, which is capable of providing enhanced lateral drainage through capillarity has been recently develop. Facilitating moisture redistribution would be a feasible approach for roads on expansive clays as they may lead uniform vertical displacements resulting in minimized cracking in the asphalt layer. Eight test sections with different geotextiles were constructed on State Highway 21 in Bastrop, Texas. The road is founded on expansive clays. A number of geotextiles, including one with enhanced lateral drainage capabilities, were incorporated to 500 feet long test sections. All sections were equipped with sensors to monitor moisture beneath the geotextiles and were periodically surveyed to document pavement distresses. Results showed that the geotextile with enhanced lateral drainage was able to maintain a uniform moisture content along the length of the soil in contact with this geosynthetic. Condition surveys showed that the geotextile with enhanced lateral drainage prevented cracking in the portion of the pavement above it. As expected, cracks often developed in areas of the pavement section beyond the extent of the geotextile. This suggested that the geotextile was capable of providing enhanced lateral drainage, although placement of the geotextile over the full width of the road (and not only under the shoulder) would be necessary to minimize the development of longitudinal cracks. In conclusion, the geotextile with enhanced lateral drainage can deal with pavements on expansive clays by improving the pavements long-term performance.

Download or read book Use of Wicking Geotextile to Dehydrate Road Embankments written by Chuang Lin and published by . This book was released on 2019 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Excess water within a pavement structure is the major cause of pavement deteriorations. A roadway is often constructed with soils compacted at the optimum water contents to achieve the best performance. After construction, the soil water content variation is controlled by the ambient environment. The base course aggregate is very sensitive to water content variations. Unfortunately, conventional drainage system can only drain gravity water, but not capillary water, and it cannot work under unsaturated conditions. Consequently, no matter how well the road is constructed, the water content is expected to increase with time and the excess water will inevitably accelerate pavement deteriorations under repetitive traffic load. This study aims at solving the excess water induced problems using a new wicking geotextile. Firstly, a series of laboratory test results were performed to characterize the mechanical and hydraulic properties of the wicking geotextile, the soil, and their interactions. After that, the laboratory test results were used as numerical simulation inputs to evaluate the performance of the wicking geotextile under different working and climatic conditions. The benefits of the wicking geotextile were quantified and incorporated into the existing pavement design methods. Then, the field performance of the wicking geotextile was continuously monitored and potential issues that might influence the long-term performance of the wicking geotextile are evaluated. Eventually, a new-bio-wicking system is proposed to further improve the drainage efficiency of the wicking geotextile. The results from laboratory tests, numerical simulations, and field observations validated the efficiency of the wicking geotextile to dehydrate road embankments"--Abstract, page iv.
Download or read book Gravel Roads written by Ken Skorseth and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
Download or read book Ground Improvement Techniques written by Patra, Nihar Ranjan and published by Vikas Publishing House. This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Systematic treatment of difficult ground as a separate paper in undergraduate and postgraduate courses is gaining ground in Indian universities. Earlier, these topics were taught under a variety of subjects like Advanced Geotechnical Engineering, Retaining Structures, Dams, Pavement Designs, Application of Geosynthetics, Application of Soil Mechanics, and so on. However, field requirement and advances in the technology make a strong case for a focused treatment of the subject which this book provides. A full-fledged paper in ground improvement techniques concentrates on the topics of soil stabilization, compaction, preloading, vertical drains, geosynthetics, in-situ reinforcements and modelling of soil reinforcement. The book provides an overview of the basic concepts of ground modifications to difficult soils in a logical and illustrative way. It teaches how to apply alternative solutions to difficult foundation problems and evaluate their effectiveness before and after construction. The text is supported by a large number of examples, review and multiple choice questions, as well as practical problems. The book is intended to serve as a textbook for undergraduate and postgraduate students of Geotechnical, Transportation, Hydraulic and Environmental Engineering, and a reference work for practising civil engineers. Salient features 1. A well researched textbook on ground improvement techniques 2. Conforms to the syllabi of all Indian universities where the subject is taught 3. Written by an expert on the subject with a decade of teaching experience

Download or read book Fundamentals of Ground Improvement Engineering written by Jeffrey Evans and published by CRC Press. This book was released on 2021-09-17 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ground improvement has been one of the most dynamic and rapidly evolving areas of geotechnical engineering and construction over the past 40 years. The need to develop sites with marginal soils has made ground improvement an increasingly important core component of geotechnical engineering curricula. Fundamentals of Ground Improvement Engineering addresses the most effective and latest cutting-edge techniques for ground improvement. Key ground improvement methods are introduced that provide readers with a thorough understanding of the theory, design principles, and construction approaches that underpin each method. Major topics are compaction, permeation grouting, vibratory methods, soil mixing, stabilization and solidification, cutoff walls, dewatering, consolidation, geosynthetics, jet grouting, ground freezing, compaction grouting, and earth retention. The book is ideal for undergraduate and graduate-level university students, as well as practitioners seeking fundamental background in these techniques. The numerous problems, with worked examples, photographs, schematics, charts and graphs make it an excellent reference and teaching tool.
